Xi'an DIEN Integrated Wastewater Treatment Equipment Helps Tianyuan Construction Group Achieve Standard Discharge for Green Construction
As a leading large comprehensive construction enterprise group in China, Tianyuan Construction Group holds dual super-grade qualifications in building and municipal engineering, with businesses spread nationwide and overseas and an annual construction output value exceeding 100 billion RMB. In the construction of various large-scale architectural, municipal, road and bridge projects, Wastewater treatment is a key link to ensure green construction and meet environmental acceptance standards. Targeting the characteristics of construction site Wastewater of Tianyuan Construction Group, Xi'an DIEN Water Treatment Equipment Co., Ltd. provides customized solutions centered on integrated Wastewater treatment equipment and plate-and-frame filter presses, efficiently solving the treatment difficulties of construction wastewater and domestic Wastewater, and supporting smooth project progress and environmental compliance.
I. Project Overview
This cooperation covers multiple large-scale architectural and municipal construction sites of Tianyuan Construction Group, mainly treating two major types of Wastewater: construction production wastewater and construction camp domestic Wastewater. Considering the characteristics of long construction cycle, compact site and large Wastewater fluctuation, Xi'an DIEN adopts modular and movable Integrated Wastewater Treatment Equipment(Click to view equipment details), matched with an efficient plate-and-frame filter press sludge treatment system. The designed daily treatment capacity meets the peak water demand of construction sites. The project provides one-stop services throughout solution design, equipment production, on-site installation, commissioning and operation & maintenance, ensuring rapid commissioning and stable operation to meet the temporary and mobile Wastewater treatment needs of construction sites.

II. Raw Water Quality Problems
The Wastewater from Tianyuan construction sites presents typical construction industry characteristics with high treatment difficulty:
Construction Production Wastewater: Mainly generated from concrete curing, pile foundation construction, vehicle and machinery cleaning, containing a large amount of sediment and cement residues, with suspended solids (SS) concentration as high as 3000-5000mg/L, alkaline pH value, as well as petroleum pollutants and a small number of heavy metal particles.
Domestic Wastewater: Originating from office and living areas of construction sites, containing high-concentration COD, ammonia nitrogen, animal and vegetable oil, detergents, with prominent organic pollution.
Common Difficulties: Water quality and quantity fluctuate drastically with construction progress, seasons and weather, making it hard for traditional processes to reach stable standards; large sludge volume with high moisture content leads to high disposal and transportation costs and potential secondary pollution.
III. Customer Requirements and Treatment Targets
Combined with construction environmental protection regulations and the green construction standards of Tianyuan Construction Group, the core project requirements are clarified as follows:
The effluent quality shall steadily meet the Class I standard of Comprehensive Wastewater Discharge Standard, and partial areas shall meet reclaimed water reuse standards (reused for site dust reduction, vehicle washing and greening irrigation).
The equipment shall feature small footprint, rapid installation and high automation, adapting to temporary site conditions and non-professional operation and maintenance needs.
Sludge shall undergo deep dewatering by plate-and-frame filter press to realize reduction and drying, facilitating compliant disposal and resource utilization.
The system shall be relocatable, supporting disassembly and transfer to new construction sites for reuse after project completion, reducing overall costs.

IV. Solution
Xi'an DIEN adopts the combined process of "Quality-based Collection + Physical-Chemical Pretreatment + Biochemical Treatment + Advanced Filtration + Sludge Dewatering", equipped with self-developed integrated Wastewater treatment equipment and plate-and-frame filter press:
Pretreatment Stage: Grilles, sand settling tanks and oil separators are used to initially remove large debris, sand and floating oil to protect subsequent equipment.
Core Treatment: Wastewater flows into the integrated Wastewater treatment equipment with built-in A/O biochemical and MBR membrane components, efficiently degrading COD, ammonia nitrogen, total phosphorus and other organic pollutants to produce clear and standard-compliant effluent.
Sludge Treatment: After concentration and conditioning, system sludge is sent to Plate-and-Frame Filter Press(Click to view equipment details) for high-pressure solid-liquid separation. The sludge moisture content is reduced to below 60% to form dried filter cakes.
Intelligent Control: The whole system adopts PLC fully automatic operation, realizing real-time water quality monitoring, automatic dosing, backwashing and sludge discharge without full-time staff on duty.
V. Treatment Effect
Remarkable treatment results have been achieved after project operation:
Standard Water Quality: Effluent SS≤15mg/L, COD≤50mg/L, ammonia nitrogen≤5mg/L, no petroleum detected, fully meeting both discharge and reuse standards.
Sludge Reduction: The plate-and-frame filter press reduces sludge volume by over 70%. Dried filter cakes can be transported for landfill or brick making for resource utilization, greatly cutting transportation and disposal costs.
Water Saving & Efficiency Improvement: Reclaimed water reuse accounts for 40% of the treated volume, saving hundreds of tons of fresh water monthly and reducing project water costs.
Convenient & Stable: The installation cycle of integrated Wastewater treatment equipment is only 7 days, operating stably without faults and adapting to complex construction site environments.
